Cable Connector Attachment

Abstract

A cable connector attachment is provided, the attachment including at least a hose fitting, wherein said hose fitting is swedged into an associated cable and threaded into a CCP; and a set screw, wherein said set screw is inserted into the hose fitting to ensure the CCP cannot vibrate loose. Optimally the set screw is a tapered screw, so that greater force is applied to the terminus end. A braided hose is disposed in mechanical communication with a stainless hose fitting and secured using one or more fasteners. The hose is securely pressed completely inside the stainless hose fitting and then crimped, and a status signal is optimally provided by a crimp machine when a predefined crimp has been completed, thereby notifying the operator of such status. Optimally the crimp measures between about 1.1-about 1.2 inches.

Claims

1. A cable connector attachment, said attachment comprising: a hose fitting, wherein said hose fitting is swedged into an associated cable and threaded into a CCP; and a set screw, wherein said set screw is inserted into the hose fitting to ensure the CCP cannot vibrate loose.

2. The cable connector attachment of claim 1, wherein the set screw is a tapered screw, so that greater force is applied to the terminus end.

3. The cable connector attachment of claim 1, further comprising a braided hose disposed in mechanical communication with a stainless hose fitting.

4. The cable connector attachment of claim 1, further comprising a plurality of connector engaging nuts.

5. The cable connector attachment of claim 3, wherein the hose is securely pressed completely inside the stainless hose fitting and then crimped.

6. The cable connector attachment of claim 5, wherein a status signal is given by a crimp machine when a predefined crimp has been completed, thereby notifying an operator of such status.

7. The cable connector attachment of claim 6, wherein said crimp measures between about 1.1-about 1.2 inches.

BRIEF DESCRIPTION OF SEVERAL EXAMPLE EMBODIMENTS

[0012] The present invention comprises creating a secure connection by swedging a hose fitting into the cable. The hose fitting is threaded into the CCP, and a set screw is inserted into the hose fitting to ensure the CCP cannot vibrate loose. In certain embodiments the set screw is a tapered screw, so that greater force is applied to the terminus end, thereby ensuring a tighter and more secure, reliable fit.

[0013] The example embodiment of FIG. 1-A shows a basic plan view of the invention. A PBOF cable is threaded into an associated CCP, and a swedged connector assures a stable seating. A set screw is drilled through the hose fitting, preferable with a tapered fit toward the terminus or distal end, so that the assembly cannot vibrate loose of the CCP. As seen in the illustrative example depicted in FIG. 1-B, a braided hose or the like is disposed in mechanical communication with a stainless hose fitting. A CCP connects the hose and fittings to an associated connector engaging nut by means of a CCP connector shell. The set screw, which in this embodiment comprises stainless steel, ensures the fitting is reliably secure and cannot shake loose due to vibration.

[0014] In the example depicted in FIG. 2-A, a plurality of suitable connector engaging nuts are shown, each with a mated set screw assembly. FIG. 2-A further shows a braided hose or the like, measured and cut to a desired length.

[0015] As shown in FIG. 2-B, the hose is then pressed into a stainless hose fitting. Optimally, the hose is securely pressed completely inside the stainless hose fitting. An appropriately sized die-train sizer is then located and placed on a crimping machine so as to receive the hose fitting assembly.

[0016] As shown in FIG. 3-A, the hose fitting is inserted from below into the die-train. For example, the hose fitting may be placed at the top edge of the die-train sizer where the hose fitting begins to slope downward. As seen in FIG. 3-B, an associated cover is then placed over the die-train.

[0017] As shown in FIG. 4-A, the die-train is then slid into place and the hose is crimped. In one embodiment, a signal is given by the crimp machine when a proper crimp has been completed so as to notify the operator of such. As seen in FIG. 4-B, a suitable crimp can measure between 1.1-1.2 inches.

[0018] As shown in FIG. 5-A, a process is initiated to pressure test the hose in a soak tank in order to detect any air leakage. In one example embodiment, a dead end attachment is connected to one end of the hose, as well as an air hose attachment at the opposite end. The fittings are then securely tightened by hand or otherwise. As seen in FIG. 5-B, an air hose is then attached. As shown in FIG. 5-C, the hose is then completely submerged in the soak tank. Finally, as shown in FIG. 5-D, air pressure is applied and an operator searches for air bubbles in the soak tank. The presence of air bubbles means the hose assembly has failed and cannot be used. In such event, the hose assembly is discarded and a new hose assembly must be made.

[0019] Turning now to FIGS. 6-A through 6-C, and assuming the hose assembly did not fail the soak tank test, the air hose is then used to push a rope string from one end of the hose fitting to the other. The wires are then taped together and tied to the rope. Pulling the rope will run the wire to the other end of the hose fitting, while the taping prevents the wires from running back into the hose.

[0020] Finally, as seen in FIG. 7-A through 7-D, the hose fitting is then connected to an associated CCP connector using the set screw. This step would typically be performed during a connector assembly build. In one example method, a light layer of multi-purpose bearing grease is applied to a tapered seal area of the connector end. The CCP connector and hose assembly are then set and connected as desired. The connection is the finally secured using a set screw, which should not be over-torqued as doing so will damage the threading on the CCP connector.

[0021] The foregoing specification is provided for illustrative purposes only, and is not intended to describe all possible aspects of the present invention. Moreover, while the invention has been shown and described in detail with respect to several exemplary embodiments, those of ordinary skill in the art will appreciate that minor changes to the description, and various other modifications, omissions and additions may also be made without departing from either the spirit or scope thereof.
